There are soo many different uniforms and no one really wants to use the standard one.
The problem is when you want to have another uniform for your crew, it's a pain the ass to change all of my bridge officers uniforms. It's also a bit rubbish when on my bridge the "Science/Tactical/Engineering" officers are wearing the default uniform.
The best to do would be able to set a uniform template for Science,Tactical and Engineering. It would save a lot of time and it would make the bridge feel more trekkie.
I think perhaps we should be able to setup a uniform style when you start a new character and all officers you get wear said uniform in their correct colours. It should also be modifyable at the Tailor.
EDIT: One thing though I think is we need more uniform options as well.
